  • A comparative study for pathogen removal using different filter media during vermifiltration

    The present study focuses on the effect of filter media (riverbed gravel, mud balls, coal and glass balls) for the removal of pathogens during vermifiltration of domestic wastewater. This novel study was conducted for the first time on different vermifilters (VFs) with different media, and pathogen removal was extensively investigated for a period of 3 months. Results indicated that vermifilter ...

  • Solid / gas separation with fabric filters

    A myriad of filter media are utilized today for separation of particulate matter in industrial gas filtration applications. These media range from single use (deposable) to semi-permanent media and include fiber, fabric, ceramic, membrane, metal mesh, and sintered metal media. Semi-permanent media are usually cleanable, either on or off-line, and are primarily intended for long-term (up to ...

  • Filtration and manganese removal

    Manganese removal through a filter bed is generally carried out and accepted by practitioners and researchers as occurring through catalytic oxidation at the surface of MnO2 coated media, although manganese passage through a coated media filter has been little investigated. To better understand the kinetics of Mn removal through a naturally coated filter, a pilot plant consisting of four filter ...

  • Self-Cleaning Filtration for Pretreatment of Membrane, UV and Ozone Water Treatment Systems

    Recent field data has shown the effectiveness of automatic self-cleaning filters in removing suspended solids down to less than 3 microns in size without flocculents, pre-coats or granulated media. Pre-treatment of ozone systems is often needed to remove organic solids that would utilize high amounts of ozone during oxidation leaving little for complete disinfection. Selfcleaning screen filters ...

Tata Power is India's largest private sector power utility with an installed generation capacity of over 2,300 MW. The CGPL UMPP, awarded on a 20 year BOOT basis, will be India’s ...

  • Wet electrostatic precipitators: A preferred technology for emission control

    The basic science behind electrostatic precipitators is as familiar and as simple as static cling. But today, this elemental force has been harnessed to a technology that is helping to remove millions of tons of toxic chemicals from our atmosphere; saving billions of dollars annually in pollution-related physical damage; and averting costly impacts on health and mortality rates for millions of ...

  • Can we bury the carbon dioxide problem?

    Seriously — carbon capture and storage could be a game-changer. Mention “carbon capture and storage” — the process of trapping carbon dioxide produced in fossil-fuel burning or other industrial processes and burying it underground — in polite company, and you’re likely to be pounced on. It’s absurdly expensive. It can never be rolled ...

  • Pyrolysis

    Introduction: Pyrolysis is formally defined as chemical decomposition induced in organic materials by heat in the absence of oxygen. In practice, it is not possible to achieve a completely oxygen-free atmosphere; actual pyrolytic systems are operated with less than stoichiometric quantities of oxygen. Because some oxygen will be present in any pyrolytic system, nominal oxidation will occur. If ...

  • Guest Post: 2012 - The Year Renewables Became a Problem

    Looking back on the energy news from 2012 there are a couple of over-riding trends. On a positive note, with significant taxpayer and/or ratepayer financial support through direct subsidies and Feed-In-Tariffs (FITs) renewable electrical generation is starting to have a major impact in several jurisdictions.  On May 25 Germany set a new record for solar energy with production of 22 GW, ...

  • In-Vessel Composting of Residential Organics

    In 1994, the Regional Municipality of Peel began work on a system for residential organic residuals collection and composting. Although Peel had been promoting backyard composting, greater diversion rates were sought. The public was surveyed to determine what level of cooperation could be expected for source separation and setting out of food, soiled paper products, yard trimmings, etc. “We knew ...
